Short answer: the Sony ULT Tower 5 for modern connections and tuning. It brings a 300W system, a 9-inch woofer, a removable 20-hour battery, 10-band app EQ and IPX4 protection plus RCA, XLR, USB-C and microphone inputs. ULT1/ULT2 modes, custom EQ and balanced XLR are practical upgrades for a wired source, DJ setup or karaoke, so choose the XP700 only for its older design priorities.

Choose the Tower 5 for modern connection options and tuning: ULT1/ULT2 modes, custom EQ and balanced XLR are practical upgrades for a wired source, DJ setup or karaoke.
Choose the XP700 only for its older design priorities: Compare the full specifications below, especially battery, inputs and transport, rather than assuming an older larger-looking cabinet is the stronger performer.
Buy the Sony ULT Tower 5. It is rated higher for sound quality, and the Sony SRS-XP700 is discontinued, so it is only available used.
If water resistance matters to you, the Sony ULT Tower 5 at IPX4 (splashing) holds up far better than the Sony SRS-XP700 at no water resistance.
